To all who-2a it may concern/L eller itknown that drains items, a (titlzen oi. the United tilt-ates 01' America, res

siding at Columbus, in. the county 01" Lowndesand State of Mississippi,has invented new and useful Improvements in Filters of tron.

which the following is a speciiicallhe object of the invention is toprovide an cliicicnt construction oi filter especially designed forwater tltor domestic and like 1 construction, "cout binatio-n andrelation of parts 01 which ajj preferred embodiment is slnnvnin thedrawlnp' wherein 1 ratus. a v p a p y 3 l igure 2 15 a front elevationoi: the same.

teri'al and maybe of any suitable dimensions to be determined. by thepurpose i'or which the apparatus is designed is divided lntericontain afiltering agent of a granular form such as graveljsand andthe like,preferably associated and arranged hereinafter par- 1 ticularlyindicated and having a bottom ll whichisperlorated lioi: coininunicationwith the clear water chamber 12? iroin wh ch e7; tends the "valvedoutletplpe or conductor L3. Said casing also encloses a settling tmugh 11 which surrounds the upperedge of the filter chamber and is incommunica tion with the inlet or primary settling chamber 15 with whichcommunlcates the supply pipe 16 having a supply valve 1'2 preferablycontrolled by a float 18 arranged in the filter chamber to the end thatthe rapidity of sup e ply may be regulatedby the contents of t iroughmaybe autoinatiwith these 1 objects in View the invention consists 1n aFigurel is a sectional view of the appa the particles of of a portionoi'the tloor of the filter chanl filterchan'lber and reduced or cut oil asthe water accumulates in said filter chamber froi'n which the waterpasses as it is filterer'l to the clear water or discharge chamber 12.

'lh'e discharge chamber is preferably provided with a conical or hopperbottom 12 sand. or like fine filtering i'naterial which may passdownward through the perforated having an outlet or vent 19 at its apexor lowermost P011113 fitted with a blow-oil or clean-out valve 20 sothat accumulations of bottmn oi the filter chamber may bev ashed I orblown out through the vent, the fact ort i the accumulations beingapparent by reason ot a gauge OITLIJSPGCBIOD. glass disposed in and incommunication with the secondary settling trough 14 adjacent to theplane o'l the upper edge of the filter chamber thereis located a valvedoverfiow vent 23 sothat when the flow of water is being reversed throughthe filtering material as hereinafter explained the water passing fromthe filter chamber into the trough 14 maybe permitted, to escape andcarry with it any accumulations removed from the surfaces of granularmaterial in the filter chamber. p i

The perforations in the bottom of the lilter chamber are preferablyprovidedwith upwardly extending nipples 24in which as illustrated may beflattened or transversely contracted orreduced to minimize the passageof filter sand or granular material orly form a filter chainberlltiadapted to therethrougb while permitting a relatively free flow of waterfrom the filter chamber to the clear vwater or discharge chamber, and[the preferred arrangement of the filtering material contemplates the useof a coarse gravel as indicated at 25 arranged upon the bottom of thefilter'chamber in a layer of adequate thickness surmounted by a layer ofrelatively fine gravel as shown at 26, at

the upper surface of which is arranged a water distributing clean-outnozzle 27pm vided' with a controlling valve 28 and provided with aseries of parallel perforated distributing tubes 29 through which watermay be distributed forcibly in an upward direction to pass through abody of sand 30 which is arranged in the filter chamber upon. the layerof fine gravel and above the plane of said clean-out nozzle.

In operation the water admitted through the supply pipe is firstsubiected to a settling -trough1 t from which in turn it passes over.

the upper edge or the wall of the filter chainher and passes downwardthrough the filter or granular filtering material to .the outlet ordischarge chamber 12 from which it may be drawn as required through theoutlet pipe :or conductor 13.

Having described the invention, what is claimed new and, useful 1s:

1. A filter having a filter chamber provided at its bottom Wlllllupstanding nipples 1 and adapted to contain granular filtering material,a clear water or discharge chamber for receiving water passing throughsaid nipples and having an outlet or discharge conductor, an inlet orprimary settling "chamber in communication with a source oi? to both ofsaid chambers over intervening barriers or walls, the discharge chamberhaving beneath the bottom of the filter chamber a downwardly contractedor tunnel shaped portion fitted at its lowermost point with a valvedvent.

2. A filter having a filter chamber providedat its bottom withupstanding nipples and adapted to contain granular filtering material, aclear water or discharge chamber for receiving water passing throughsaid nipples and having an outletor discharge conductor, an inlet orprimary settling chamber in communication with a sourceot supply, and asecondary settling trough interposed'between the primary settlingchamber andthe filtering chamliiorand accessible to both of saidchambers over intervening barriersor walls, said primary settlingchamber being provided in communication with its bottom \vitl'r a valveddischarge openin 3, It filter having a filter chamlrscr pro vided at itsbottom with upstanding nipples and adapter to contain. granularfiltering material, a clear water or discharge cl amber for receivingwater passing through said nipples and having an outlet or dischargeconductor, an inlet or primary settling chamber in communication with asource ot supply and a secondary settling trough interposed between theprimary settling:- chamber and the filtering chamber and accessible toboth ot said chambers ovcr intervening barriers or walls, a valvedoverflow outlet being arranged in communication with said interposedsecondary settlingtrough.

4. A filter having a filter chamber provided with a perforated bottom.inlet and discharge chambers in communication with the filter-chamberrespectively at its upper edge and at its bottom. said filter chamberbeing adapted to contain granular filtering material, and a valved cleanout nozzle arranged in the filtering cluunber and provided withhorizontally disposed pcri" 'u'at d distributing tubes.

53. Zr filter having a filter chamber lvided with a perforated bottom,inlet and discharge chambers in communication with tl'ie filter chamberrespectively at its upper edge and at its bottom. said filter chamberbeing adapted to contain granular filtering i'nateriali and a valvedclcanout nozzle arranged in the filtering chamber and provided withhorizontally disposed perforated distributing tubes with theirperitoratimis directed upwardly, said nozzle being disposed in a planebelow the upper surface of the contained filtering material.

('5. A filter having a filter chamber provided with a perto 'ated bottom*all, a clear ater or discharge chamber for receiving water from thefilter chamber and provided wth an outlet conductor, an inlet or primarysettling chamber, a secondanv settling trough interposed between theprinniry sottling chamber, and the filter chamber, a valve controlledsupply pipe comnnlnicating with the primary settling chamber, and afloat controlling said valve and act-uatable by the fluid contents ofthe filter chamber.
